IMPROVEMENT IN FLUTING-MACHINES.

S ecification forming part of Letters Patent No. 168354., dated October 19, 1875; application filed September '7, 1875.

To all whom it may concew:

Be it known that I, HERMANN ALBRECHT, of Philadelphia, Pennsylvania, have invented certain Improvements in Fluting-Machines, ot' which the following is a specification:

The main object of my invention is to construct a flutingmachine, the upper roller ot' which shall be exposed and unencumbered with obstructions tending to interfere With the free use of the machine; and this object I attain in the nanne' which 1 will now proceed to describe, reference being' had to the accompaying drawing, in which- Figure 1 isa front View of my improved fluting-machine; Fig. 2, a plan View; Fig. 3, a Vertical section on the line 1 2 5 Fig. 4, an end View, and Fig. 5 a sectional plan on the line 3 4. 4

A is the base of the machine, and to this base is secured the frame B, which has bearings a a' for the journal I of the lower flutingroller D, the end c of the said journal 'being arranged for thereception of the usual handle.

An arm, d, projects from and forms a part of the frame or stand B, and the turned-up end of this arin has a projection adapted to the interior of the lower fiuting-roller, and serving as the outer hearing for the same.

It maybe here remarked that both bearings a and a' are not necessary, but it is essential to my invention that the lower fiutingroller should be supported at each end. This lower fluting-roller is combined With au upper roller having bearings at one end only, so that the latter roller may be exposed and nnencunbered with an outer bearing, which tends to interfere with the convenient use of the machine, and so that the lower roller supported at each end may serve as a support for the upper overha'n gin g roller.

The journal e of the upper roller has its bearings d' d' on a frame, G, which is pivoted to the frame or stand B, so that the upper roller can' be readily elevated when the fabric to be fluted has to be introduced between the rollers. An arm, m, irojects from the pivoted frame G, and this arm is, during the operation of the machine, held in place by a catch-lever, a. A screw, p, passes through a projection, w, of the pivoted frame, and between the end of this screw and the arm m intervenes a spira spring, q.

As these devices for looking, releasing, and imparting pressure to the upper roller are described in a prior application for a patent filed by me on the 6th August, 1875, further description here will be unnecessary.

The'halfbearings a a' of the journal b of the lower roller are more easily made than whole bearings, but require the use of a hook, H, connected to the frame, as shown in Fig. 3, so as to prevent the journal b from rising.

I claim as my invention- 1. The combination in a fluting-machine, of a lower fluting-roller, supported at both ends by bearings, with an upper fluting-roller, having bearings at one end only.

' 2. The combination ot' the upper flutingroller D', 'with the pivoted frame G, and its two bearings, d' d', adapted to the journal of the said roller, as setforth.

In testimony whereoflhave signed myname to this specification in the presence of two subscrihing witnesses.
